The challenge of network-centric security

For 30 years, enterprises have relied on network-centric methods to connect users to the network, and by extension the applications running on it. But the way users work has changed, and with applications moving to cloud, the perimeter has extended to the internet. This renders network-centric solutions, like remote access VPNs, obsolete.

Common pitfalls of network-centric approaches:

Places users on-net which increases risk

Provides a poor end user experience

Inbound connections create opportunity for DDoS attacks

Requires appliances, ACLs and FW policies

No ability to provide application segmentation

Lack of visibility into app-related activity

Zscaler Private Access

Enabling user and application-centric security

Zscaler Private Access (ZPA) is a cloud service from Zscaler that provides zero trust, secure remote access to internal applications running on cloud or data center. With ZPA, applications are never exposed to the internet, making them completely invisible to unauthorized users. The service enables the applications to connect to users via inside-out connectivity versus extending the network to them. Users are never placed on the network. It provides a software-defined perimeter that works across any IT environments, any device and any internal application.

Fully software-defined perimeter service

Software-defined. Built for zero trust networking

Zscaler Private Access takes a user and application-centric approach to network security. It ensures that only authorized users and devices have access to specific internal applications. Rather than relying on physical or virtual appliances, ZPA uses lightweight infrastructure agnostic software to connect both users and applications to the Zscaler Security Cloud, where the brokered connection is stitched together.

Discover and secure shadow IT applications

Many enterprise teams are unaware of the sheer number of applications in their environment. ZPA identifies previously undiscovered internal applications running in the datacenter or on public cloud infrastructure. Once identified, admins can set granular policies for each application, ensuring the environment remains secure and controlled. This, combined with ZPA’s ability to make known applications invisible to unauthorized users, reduces the attack surface dramatically.

Choose application segmentation, not network segmentation

In the past admins needed to segment networks to ensure secure user connections. Today, enterprises use ZPA to control which users access which applications. Admins can easily set granular policies at the application level for specific users, users groups, applications, application groups and associated subdomains.
